DEVICE FOR TURNING MUSIC Filed Sept. 9, 1929 2 Sheets-Sheet 2 INVENTOR I ATTOR EY Patented Nov. 22, 1932 UNITED STATES EMMY MAI-IR, OF DALLAS, TEXAS DEVICE FOR TURNING MUSIC Application filed September This invention relates to new and useful improvements in music racks, and the primary object of the invention is to provide means for holding the music upon the rack and for turning the pages of music with the foot, leaving both hands of the musician free to play the instrument.

The invention will be clearly understood from a perusal of the following detailed description, taken in connection with the accompanying drawings, forming part of this specification.

Figure 1 is a front elevational view of the upper part of a music rack or board upon which the sheets of music are flattened or spread out, and illustrating in part the means for turning the pages or sheets of music.

Figure 2 is a similar view, illustrating the reverse side of the board.

90 Figure 3 is a side elevational view of the stand, supporting the board.

Figures 4, 5 and 6, are detail sectional views of the mechanism on the board for turning the music, and

Figure 7 is a partial cross-sectional View, taken along the line 7 -7 of Figure 1.

Referring more closely to the drawings, in Figure 3 is shown an ordinary conventional music stand of well known construction, the 39 board or music support being removed. This stand consists of a central hollow post 1, with adjustable legs 2, and provided with the links 4 for rigidity. The stand being old in the art, no claim, per se, is made therefor. A

" second hollow post 5 is slidable within the post 1 for extensible purposes, to adjust the board or rack to required height. The post 5 carries a slidable angular element 6 for connecting the board or rack 7 to the posts,

the element 6 adapted to be inserted in a member 8, carried on a vertically disposed strip 9,

secured to the board 7. In this manner, the

board 7 is held in a rearwardly-inclined position, convenient for the easy reading of the music placed thereon. A shelf 10 supports the sheets of music against the board.

The invention consists essentially of a plurality of angular arms, comprising a right angled element 11, a collar 12 and a curved member 13. The collars are loosely mounted Serial No. 391,473.

on a short rod 5 depending from the shelf 10 and are held in position by a small ring 14. Figure 1 illustrates the normal position of the arms. v

For swinging these arms across the face of the board 7, there is provided, on the reverse side of the board, a bell crank 15, a slidable bar 16 and a spring 17, the latter being enclosed in a housing 18. Loosely connected to I the bar 16 and associated with the spring is a rod 19. This bar 16 has a tooth 20 for engagement with the curved member 13, for the purpose of engaging the arms in their travel across the board, as will be hereinafter described.

The bell crank 15 is pivoted at 21 to the back of the board 7 and is connected at one end to the rod 19 by a link 22. The other end of the bell crank has pivoted thereto an element 24 which may be either a small rod, wire, chain or the like and is connected at its lower end, see Figure 3, to a bar 25, pivoted to one of the legs 2. This bar is provided with a member 26 for depressing the bar in operation of the device.

In operation, the sheets of music indicated at 28, are placed upon the shelf 10, and inclined rearwardly against the board 7 in the manner shown by broken lines in Figure 1. The tops of the sheets extending above the board, rest against the strip 9. Then there is a small rod or element 10 which is placed in the center of the sheets to hold them in central position on the board, the lower end of this rod being locked in a notch in the shelf, clearly shown in Figure 7. Each arm element 11 carries a small spring 11 for holding each sheet of music securely on the element 11. However, this spring may be dispensed with if desired. 9

Vhen the foot depresses the bar 25, the element 24 will pull the upper end of the bell crank downward and move its other end laterally. This will slide the bar 16 held in alinement with the members 15 by a strip 20 and cause the tooth 20 to pull one of the arms over across the board from right to left, reversing one sheet of the music. The short rod 5 is so disposed below the shelf in the opening A that the arms will lie flat on the board. Figure 7 shows one of the arms in normal and operative position, the tooth 20 being engaged in the curved member 13, after the arm has been moved over and turned or reversed a sheet, the spring 17 retracts the rod 19 and bar 20 to the position shown in Figure 2.

The disclosure, While illustrative of a complete and practical working embodiment of the invention is capable of modifications, such as will be in keeping with the appended claims.

What is claimed as new is:

1. A device for turning music, in combination with a stand, comprising a support for the music,,a rod depending from the support and upon which are mounted for rotation a plurality of members, each of said members for engagement with sheets or pages of music 2 3) and each having a collar for supporting the member upon said rod, a music-engaging arm formed integrally with said collar, said collar having an integrally-formed curved elementtfor engagement with a bar in turning 13 the music; a bell crank pivoted to said music support, a slidablebar pivoted to one end of said bell crank, said bar having a. memher to successively engage with the curved element of said collar as the music is turned; means for actuating said slidable bar and means for returning the bar to normal inoperative position.

2. A device for turning music as claimed in claim 1, said means for actuating said bar 35 comprising a rod connected to one end of said bell crank and adapted to movement by a foot lever, whereby said bar is slid in one direction when the bell crank is operated; a keeper and a spring disposed therein on an axial line with said slidable bar; a rod associated with said spring and having one end thereof pivoted to one end of said slidable bar; the operation of the device being such that when the .foot lever is depressed Saidbar will be slid or moved in one direction and turning a piece of music in that direction, said bar moving against said spring, the latter returning the bar to inoperative po- I sition on expansion. In testimony whereof I afiix my signature.
